If you want to understand something of the exercise of power in the early Roman Empire, this is for you.
Having seen "The Caesars" when I was at school, I could not understand the swooning praise heaped on the Derek Jacobi (who was about the best thing in it) "I Claudius" which is overwhelmingly superficial, inaccurate and a kind of infantile, tabloid version of the far better novels by Robert Graves (who had a sense of humour though tyou wouldn't guess it from this travesty).
The real Augustus, to take just one example, was physically slight, intellectually subtle and personally formidable so casting Brian Blessed (of all people - was it some kind of grotesque joke?) in that role in "I Claudius" was grotesquely wrong. Roland Culver was an infinitely better choice.
This was a series about the realities of power in any period - and rather closely followed the surviving record of the sophisticated and lurid Roman historian Suetonius.
Of course, the B&W picture is sometimes rather dodgy but it is probably as good as we will get - and TV production was pretty rough in 1968 compared to today's digitalised everything and spectacular nothingness.
